I like more information than a buzzer. This is in the sailboat, facing my head as I sleep. It can have any information I want on it: heading, location, wind speed or direction, even engine readings. It is backlit and dimmable at night, and has an alarm buzzer you can set for a variety of things. Most vendors have a similar display head.
I often set it to show wind speed, direction, heading, and depth. Sometimes DTW from the anchoring point. If the heading or wind has changed, then maybe the anchor needs to be checked as it will have veered or upset. If the wind it up maybe I should check. If my DTW to my original position is increasing, why?
Most the time, glance at it and go back to sleep.
If you only have a buzzer, then you have no situational awareness.
